1. That isn't the whole method.
2. Server resets are random to stop people from trying this.
3. The window for this only about one minute (i.e. you have to do it less than one minute before the server reset which happens randomly sometime in a 4 hour window)
4. This behavior is monitored because people were still trying to do it.
5. SB has zero tolerance so if they see you trying this around server reset they ban first and often don't ask questions.
6. While theoretically it still works no one can prove it because the timing, watchdogs, and the fact you only get one chance per day to try.
